| 摘 要： | 诱饵的存在性检测是对抗拖曳式有源雷达诱饵干扰的前提,也是决定抗干扰效果的重要因素.当导引头雷达发射多个不同频率的脉冲信号时,在一定的检测处理时长内目标回波信号幅度服从瑞利分布,而诱饵干扰信号则是幅度固定的.基于导引头雷达波束内诱饵存在导致的回波特征变化,通过提取诱饵存在/不存在两种情况下雷达接收回波信号的幅度特征差异以...

| Abstract: | The detection of the presence of the decoy is the foundation of countering the towed radar active decoy(TRAD) and it determines the effect of the ECCM.When the radar seeker transmits several different frequency pulses,the echo amplitude of the target follows the Rayleigh distribution and that of the decoy is assumed fixed.This paper presents an analysis of the variation of the echo characteristic in the radar beam and when a towed decoy exists extracts the feature distinction of the echoes amplitude and the... |
